PAT testing City of London — financial offices, law firms and managed workspaces.
The City of London is one of the world's most densely occupied commercial districts. We deliver PAT testing programmes designed around the access restrictions, security requirements and out-of-hours constraints of City office buildings — from Canary Wharf-adjacent Aldgate to the Barbican, Moorgate, Liverpool Street and St Paul's. We work with building managers, facilities teams and managing agents across the Square Mile.
Our City & Guilds qualified engineers carry out commercial PAT testing, portable appliance testing and electrical equipment testing for City of London financial institutions, law firms, insurance companies, managed office buildings and co-working spaces — producing itemised test registers, pass/fail labels and compliance certificates that satisfy your electrical safety obligations under the Electricity at Work Regulations 1989.
